Postcentral sulcus
Postcentral Sulcus
The Postcentral Sulcus (/poʊstˈsɛntrəl ˈsʌlkəs/) is a prominent structure in the human brain, specifically in the parietal lobe.
Etymology
The term "Postcentral Sulcus" is derived from Latin, where "post" means after, "central" refers to the central position, and "sulcus" means groove. Thus, it refers to the groove located after the central sulcus in the brain.
Description
The Postcentral Sulcus is a groove in the parietal lobe of the brain, located posterior to the central sulcus. It runs roughly parallel to the central sulcus. The postcentral gyrus, which is the primary somatosensory cortex responsible for processing tactile information, is located immediately posterior to this sulcus.
